Simplifying Algebraic Expressions: (-a^2-5ab+3b^2)-(3a^2-2ab+3b^2)
This article will guide you through simplifying the algebraic expression (-a^2-5ab+3b^2)-(3a^2-2ab+3b^2).
Understanding the Problem
We are given two expressions, one subtracted from the other. To simplify, we need to combine like terms.
Simplifying the Expression
-
Distribute the negative sign: The minus sign in front of the second parenthesis means we multiply each term inside by -1.
(-a^2 - 5ab + 3b^2) + (-1 * 3a^2) + (-1 * -2ab) + (-1 * 3b^2)
-
Simplify: -a^2 - 5ab + 3b^2 - 3a^2 + 2ab - 3b^2
-
Combine like terms: Terms with the same variables and exponents can be combined. (-a^2 - 3a^2) + (-5ab + 2ab) + (3b^2 - 3b^2)
-
Final result: -4a^2 - 3ab
Conclusion
Therefore, the simplified form of the algebraic expression (-a^2-5ab+3b^2)-(3a^2-2ab+3b^2) is -4a^2 - 3ab.
